title: Carboxymethyl cellulase and cellobiase production by Clostridium acetobutylicum in an industrial fermentation medium.
abstract: The production of a carboxymethyl cellulase and a cellobiase by Clostridium acetobutylicum was demonstrated. In liquid medium the carboxymethyl cellulase was induced by molasses, and it was not repressed by glucose. Optimum carboxymethyl cellulase activity occurred at pH 4.6 and 37 degrees C.
